How to create your own basic image in docker

1. Local Image

For example, you can package your development environment with the name centos6-base.tar. then, you can use centos6-base.tar as the benchmark image in docker.

 

1. Create your own image and place it in the/root directory:

 

1. # Tar -- Numeric-owner -- exclude =/proc -- exclude =/sys-CVF centos6-base.tar/

For example, only the files (.tar, .tar.gz,. tgz,. bzip,. Tar. xz, or. txz) are supported.

2. Import the produced centos and command: centos6-base:

1. # Cat centos6-base.tar | docker import-centos6-base

3. Now you can run it (test to view the kernel ):

1. # Docker run-I-t centos6-base CAT/etc/RedHat-release

Ii. Local directory

If you put centos-base.tar in the/OPT directory, this command can be (unverified ):

$ Sudo tar-C. | docker import-/OPT

Ii. Remote Image

1. Simple operation:

$ Sudo docker import http://example.com/exampleimage.tgz
